   An architect is responsible for designing a new vSphere-based solution to meet the following customer requirements: The solution must support component-level redundancy. The solution must support physical segregation of management and workload traffic. Any traffic from virtual infrastructure-level operations (such as migrations of workloads between hosts within a cluster) must not impact any workload. The solution should react to any substantial impact of physical network traffic to ensure workload traffic is unaffected. In response to this requirement, the architect makes the following logical design decisions: The solution will separate vSphere management traffic from all other network traffic. The solution will ensure that all replication and vMotion traffic will be separated from all other traffic. The solution will separate workload traffic from all other network traffic. The customer has a hardware standard for physical VMware ESXi host servers that includes 6 x 10 GbE network. Which three physical design decisions should the architect make to meet the requirements? (Choose three.)

   • AThe solution will configure the Route Based on Source MAC Hash load balancing method.
   • BThe solution will deploy three (3) vSphere standard switches each with a single uplink port group.
   • CThe solution will configure the six (6) available network connections into load balanced pairs.
   • DThe solution will deploy a vSphere distributed switch with three (3) uplink port groups.
   • EThe solution will configure the six (6) available network connections into a single load balanced group.
   • FThe solution will configure the Route Based on Physical NIC Load load balancing method.

   An architect is responsible for the lifecycle management design for a brownfield vSphere-based solution. The following information has been provided during initial meetings around the new solution: Existing heterogeneous server hardware will be used to provide the hosting platform. The available hardware is: 10 servers that contain 2 x 20-Core Intel Xeon processors and 512 GB RAM from Vendor A 10 servers that contain 2 x 24-Core Intel Xeon processors and 768 GB RAM from Vendor A 20 servers that contain 2 x 16-Core AMD EPYC processors and 512 GB RAM from Vendor B 10 servers that contain 1 x 24-Core AMD EPYC processors and 256 GB RAM from Vendor C All of the hardware is currently listed on the VMware Hardware Compatibility List (HCL). All existing server hardware has 36 months vendor support remaining. The requirements from the customer are: REQ001 - The solution must support the hosting of 5,000 workloads across two physical sites. REQ002 - The solution should minimize the number of clusters. REQ003 - The solution must ensure that there is no impact to service when completing upgrades. Given the resource requirements needed for the solution, the architect has calculated that all of the existing servers will be required to provide sufficient resources for the new environment. The Intel-based servers will be deployed to the primary site and the AMD-based servers will be deployed to the secondary site. Which four additional design decisions should the architect make to ensure all requirements can be met? (Choose four.)

   • AThe solution will create an Intel-based 20-node vSphere cluster in the primary site and an AMD-based 30-node vSphere cluster in the secondary site.
   • BThe solution will use VMware SDDC Manager to perform lifecycle management of the solution.
   • CThe solution will ensure each vSphere cluster supports a minimum of N + 1 redundancy.
   • DThe solution will use vSphere Lifecycle Manager images to update and upgrade vSphere ESXi hosts in the secondary site.
   • EThe solution will use vSphere Lifecycle Manager baselines to perform patching and upgrading of vSphere ESXi hosts in the secondary site.
   • FThe solution will use vSphere Lifecycle Manager images to update and upgrade vSphere ESXi hosts in the primary site.
   • GThe solution will ensure each vSphere cluster is configured with Distributed Power Management (DPM).

   An architect is designing a new vSphere solution. The following information has been gathered during the design workshops with the customer: The solution will be deployed into two availability zones (AZs) The solution will be configured as a single stretched cluster with shared storage across the two AZs Production and Development workloads will run across both AZs The cluster is configured as N + 1 The architect needs to ensure that, in the event of a host failure during maintenance of another host in the cluster, only the Production workloads are recovered. What should the architect include in the design to meet this requirement?

   • AConfigure vSphere HA VM Monitoring to VM and Application Monitoring Set the VM monitoring sensitivity to Custom
   • BConfigure vSphere HA VM Monitoring to VM Monitoring only Set the VM monitoring sensitivity to Preset of High
   • CConfigure vSphere HA Host Failure Response to Restart VMs Set the Development VMs to Disabled as the Restart Priority
   • DConfigure vSphere HA Host Failure Response to Restart VMs Set the cluster default Restart VM Restart Priority to Highest
